SINK-COUPLING.

SPECIFICATION forming part of Letters Patent No. 406,272, dated July 2, 1889.

Application filed March '7, 1889.

Serial No. 302,263. (No model.)

To all whomt't may concern.-

Be it known that I, LOUIS J. EUVRARD, of Montclair, in the county of Essex and State of New Jersey, have invented a new and usefulby which waste-pipes are connect-ed to castiron and other sinks.

In the use of the ordinary coupling-ring much annoyance, waste of time, and consequent expense are involved in simply replacing it, because of the necessity of entirely breaking the joint and bending the pipe, or taking out the sink, in order to slip a new ring over the pipe to embrace it whenever from any cause thering breaks after the joint has been made, while on new work as well as oldthe coupling-ring, which must necessarily embrace the pipe'while it is being fitted to the collar on the sink, is in the way of the workman and is apt to indent and mar the finished surface of the pipe.

The object of my invention is to overcome these disadvantages and to furnish a coupling-piece in place of the ring, which, while it will fulfill perfectly all of the functions of the ring, may be applied to the joint after the pipe has been fitted.

In the accompanying drawings, Figure 1 is a view in perspective of my improved sinkcoupling device; Fig. 2, a plan view thereof; Fig. 3, a cross-section in line a: as of Fig. 2; Fig. 4:, a diametric section of the coupling as applied to a sink to support and secure the waste-pipe.

This improved coupling is formed in two ion A, to pass between embracing ears or lugs D l) and H H, formed opposite thereto at the ends of the straight face of the opposite division B, as shown in Figs. 1 and 3, thereby forming interlocking joints, whichgserve. to support and insure an exact registry of the two divisions when they are brought together. For greater convenience, thelugs or ears 0 D forming one of these joints may be extended or enlarged sufficiently to receive a transverse pivot-pin E, as shown in Figs. 1 and 2, to constitute a hinge upon which the two divisions may be swung open, as shown by the dotted line3 in Fig. 2.

The customary slotted offsets F F, by which the coupling is made fast to the sink, are made to project from the curved margin of each division on a diametric line at a right angle to the line on which the two divisions part.

In the use of my invention the end of the lead waste-pipe I for the sink J is fitted in the customary manner over the projecting flange or collar K, encircling the discharge-aperture in the sink. After the joint has been properly fitted the annular hinged coupling-pieceA Bis opened (see dotted lines, Fig. 2) sufficiently to permit it to embrace the end of the pipe I, and is then closed upon it, as shown in Fig. 4, so as to fully encircle the same. It is then drawn up toward the sink by means of the sink-bolts L L, passing through the slotted offsets F F, so as to firmly clamp and support the joint and uphold the pipe I.

hen it becomes necessary to repair the joint, the coupling is readily removed by the withdrawal of the bolts L L without the neon one face only, and having slotted offsets projecting outwardly midway the curved rim of each, and ears or lugs projecting at each end of the straight edge of the one division to pass between embracing ears or lugs formed opposite thereto at the ends of the straight edge of the opposite division,'and thereby form interlocking joints, which insure the proper registry of the divisions, substantially in the manner and for the purpose herein set ro forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

LOUIS J. EUVRARD. Witnesses:
